Next: OPTIONAL STEP 1 Up: ALSCRIPT Command Summary Previous: STEP 1 COMMANDS


BLOCK_FILE <string>

Gives the name of the file that contains the multiple sequence alignment to be formatted. File names should be fully qualified i.e. not relative to the current directory. If no block file command is given, ALSCRIPT will expect to read the block file from standard input.

OUTPUT_FILE <string>

Defines the output file name. This command should be near the beginning of the command list. e.g. OUTPUT_FILE

You MUST define an output file unless the -p option (See Alternative ways of invoking ALSCRIPT) is used.

DEFINE_FONT <int> <string> (<int>/DEFAULT)/(REL <float>)

Defines a font to use later: e.g.

DEFINE_FONT 0 Helvetica 10
DEFINE_FONT 2 Times-Roman 2

defines font number 0 to be 10 point Helvetica, and font number 2 to be 2 point Times-Roman. Font 0 is always used as the default font. You MUST define at least the font 0 font.


sets font 3 to be Times-Roman at whatever the default pointsize is as set by the POINTSIZE command.

DEFINE_FONT 4 Helvetica REL 0.5

sets font 4 to be helvetica at half the default pointsize.

NOTE: Font names must be written exactly as shown in PostScript Fonts.


Signals the end of the STEP 1 commands.
